Rewrite interrupt handling functionality for the i386 port. Separated
functionality into separate CPU and Architecture components.
It appears as if the i386 interrupt handler functionality was intended
to allow multiple handlers to be installed for a given interrupt.
Unfortunately, this functionality was not fully implemented and also
had the problem that irq_free_handler() does not allow the passing
of the handler function pointer and therefore could never be used to
free specific handlers that had been installed for a given IRQ.
There were also various issues with array bounds not being fully
tested.
I had two objectives in mind for the new implementation:
1) Keep the implementation as similar as possible to existing
implementations. To that end, I have used the leon2/3
implementations as the reference
2) Seperate CPU and Architecture specific elements. All specific i386
interrupt functionality is now in cpu/i386/ with the high level
API and architecture specific code in lib_i386. Functionality
specific to the PC/AT architecture (i.e. cascaded i8259 PICs) has
been further split out into an individual file to allow for the
implementation of the PIC architecture of the SC520 CPU (supports
more IRQs)

A recent gcc added a new unaligned rodata section called '.rodata.str1.1',
which needs to be added the the linker script. Instead of just adding this
one section, we use a wildcard ".rodata*" to get all rodata linker section
gcc has now and might add in the future.
However, '*(.rodata*)' by itself will result in sub-optimal section
ordering. The sections will be sorted by object file, which causes extra
padding between the unaligned rodata.str.1.1 of one object file and the
aligned rodata of the next object file. This is easy to fix by using the
SORT_BY_ALIGNMENT command.
This patch has not be tested one most of the boards modified. Some boards
have a linker script that looks something like this:
*(.text)
. = ALIGN(16);
*(.rodata)
*(.rodata.str1.4)
*(.eh_frame)
I change this to:
*(.text)
. = ALIGN(16);
*(.eh_frame)
*(SORT_BY_ALIGNMENT(SORT_BY_NAME(.rodata*)))
This means the start of rodata will no longer be 16 bytes aligned.
However, the boundary between text and rodata/eh_frame is still aligned to
16 bytes, which is what I think the real purpose of the ALIGN call is.

The environment is the canonical storage location of the mac address, so
we're killing off the global data location and moving everything to
querying the env directly.
In the ppc case, these things are part of the legacy ABI, so keep them
around but mark them as legacy so no new code will touch them.
Also stop calling load_sernum_ethaddr() since all boards now implement
this as a stub.

It also converts the rarely used 'q' length modifier to the common 'L'

While this new code is a bit larger (~1k .text), most of it should be made
up by converting the existing ip/mac address code to use format modifiers.
